What is an elevator?
Also known as an elevator in some countries, it is a
vertical means of transportation used in buildings to raise and lower people
and goods between different levels. It is an essential part of our daily life,
providing comfort and ease of movement inside high-rise buildings and
multi-storey houses. The elevator usually consists of a car carrying people or
goods, and a mechanism that controls its movement by an electrical or hydraulic
system. Elevators increase efficiency and save time compared to internal
staircases, and are essential in facilitating access to different levels in
modern buildings..
How an elevator works
The operation of the elevator depends on a complex and
elaborate system that allows the car to be raised and lowered inside the main
shaft of the elevator smoothly and safely. Here is a general explanation of how
the elevator works:
- Car
and column: The elevator usually consists of the car that carries
passengers or goods, and the main column that extends through the building
between the different levels.
- Elevator
motor: There is an electric motor at the bottom base of the column, and
this motor is responsible for generating the vertical movement of the car.
- Electrical
and control systems: Elevators contain complex control systems that allow
the passenger to specify the desired destination, regulate speed, and stop
the elevator at the appropriate level..
- Cables
or Ropes: Traditional lifts use cables or ropes to connect the car to the
lift motor and guide it onto the shaft. In modern elevators, stainless
steel chains or ropes may be used to ensure durability.
- Doors
and sensors: Elevators contain doors that open and close automatically at
each level. Sensors installed on the doors detect the presence of
obstacles in front of the doors and prevent them from closing if there is
something abnormal.
When the user's destination is selected and the appropriate
button is pressed, the motor starts to run the cables or ropes in the
appropriate direction. The speed and stop of the elevator are adjusted
precisely using control systems. When the elevator reaches the required level,
the doors automatically open to allow passengers to exit. Thus, safe and
efficient transportation between different levels within the building is
achieved.
Elevator safety
Lift security is crucial to ensuring passenger safety and a
safe user experience. Many systems and features have been developed to ensure
elevator security, and these are some of the main points related to elevator
security:
- Regular
inspection and maintenance systems: Periodic inspections and maintenance
of elevators are conducted by qualified maintenance technicians to ensure
that all parts are working properly. This includes checking cables, doors,
electrical and mechanical systems.
- Security
capsule system: There is usually a safety capsule system in case the
elevator falls. This system is activated when the fall exceeds a certain
speed, directing the vehicle to the closest level and providing a safe
landing experience for passengers.
- Speed
control systems: Speed control systems are used to maintain the
elevator speed within safe limits. If the speed exceeds the safe level,
the vehicle is steered to the nearest level quickly and effectively.
- Door
sensors: The doors are equipped with sensors that detect any obstacles in
the closing path. If an abnormality is detected, it prevents the doors
from closing and reopens them automatically to prevent any harm to the
occupants.
- Warning
signals and emergency procedures: Elevators usually have emergency buttons
and warning lights for passengers to react in an emergency, which can be
used to communicate with the operator or to deal with emergency situations..
Overall, elevators are considered a safe and reliable means
of transportation in modern buildings, and the industry follows strict safety
and quality standards to maintain the safety of passengers..
The elevator falls
An elevator fall is a rare accident that rarely occurs due
to many safety procedures and systems present in the design of modern
elevators. However, this must be handled with caution, as it can have a serious
impact on safety.
If the elevator falls, the main safety system intervenes to
prevent the free fall and keep passengers safe. This system usually includes
what is known as an “emergency cable” and guide devices designed to reduce the
speed of the fall and bring the vehicle to a quick and safe stop.
Elevator safety depends largely on regular maintenance and
regular technical checks. If these aspects are carefully considered, the risk
of an elevator falling can be reduced to a minimum.
Although elevator falls are considered a rare accident,
building owners and elevator operators must comply with all safety regulations
and standards to ensure the safety of passengers and reduce the risk of such
accidents occurring..
Aerial elevator
The pneumatic elevator is a modern transportation technology
that differs from traditional elevators that rely on cables and hydraulic
systems. The pneumatic lift relies on the principle of atmospheric pressure to
raise and lower the car inside the main shaft.
This type of elevator has several advantages, including a
higher lifting speed than traditional elevators can provide, and it works by
generating a vacuum or air pressure inside the column to raise and lower the
car. The pressure is precisely adjusted to ensure the desired movement is
achieved smoothly and safely.
Thanks to its innovative design, the aerial lift can be
easily installed in modern buildings and is a good choice for buildings looking
to save extra space and for bold architectural designs. In addition, this type
of elevator is more energy efficient and includes an advanced safety system to
protect passengers.
An aerial lift can be an exciting and innovative option for
modern building owners looking to improve the user experience and provide an
innovative solution for vertical transportation..
The price of an escalator in Egypt
The price of an escalator in Egypt depends on many factors,
including specifications, brand, quality, and features. The price of an
escalator in Egypt generally ranges from 10,000 Egyptian pounds to 30,000
Egyptian pounds or more, and this depends on the model, size and additional
functions..
It is important to keep in mind that there are price
variations between different brands and sellers. There may also be additional
costs for installation and regular maintenance. It's always a good idea to
research and compare several options and talk to escalator professionals to
ensure you get a quality product that meets your needs and budget..
Elevator door sensor
The elevator door sensor is a crucial part of the safety and
operation system of modern elevators. This sensor is usually installed on
elevator doors, and its main function is to detect the presence of objects or
people along the door area. When an object is detected in the way of the doors,
a protection system is activated that stops the doors from closing, keeping
occupants safe and preventing harm..
This sensor usually uses advanced technologies such as
infrared or ultraviolet light to detect anything that crosses the door area.
When a potential obstruction is detected, the doors are immediately stopped and
an audio or visual signal is issued to alert passengers to wait until the
obstruction is removed..
The elevator door sensor is considered one of the essential safety elements in the elevator system, as it contributes to reducing injuries and severe accidents and ensuring safe use of the elevator. The technology of these devices is constantly evolving to increase the safety and efficiency ofmodern building elevators.
